Zylicz-Stachula A, Zolnierkiewicz O, Jasiecki J, Skowron PM.Genomics and metagenomics are currently leading research areas, with DNA sequences accumulating at an exponential rate. Although enormous advances in DNA sequencing technologies are taking place, progress is frequently limited by factors such as genomic contig assembly and generation of representative libraries. A number of DNA fragmentation methods, such as hydrodynamic sharing, sonication or DNase I fragmentation, have various drawbacks, including DNA damage, poor fragmentation control, irreproducibility and non-overlapping DNA segment representation. Improvements in these limited DNA scissi...
Wang CC, Hartmann-Fischbach P, Krueger TR, Wells TL, Feineman AR, Compton JC.Dermorphin and HYP(6) -dermorphin are hepta-peptides and natural opioids originally isolated from the skin of South American frogs. They are more potent than morphine but less likely to produce drug tolerance and addiction. These properties make them ideal candidates for the doping of racehorses to enhance performance during competition. Dermorphin was recently classified as a Class I drug by Racing Commissioners International (RCI), indicating that it is a banned substance in equine athletes. To enforce this ban, a fast and sensitive method was developed for dermorphin and HYP(6)-dermorphin a...
Yan W, Saleem MH, McDonough P, McDonough SP, Divers TJ, Chang YF.Leptospira immunoglobulin (Ig)-like (Lig) proteins are a novel family of surface-associated proteins in which the N-terminal 630 amino acids are conserved. In this study, we truncated the LigA conserved region into 7 fragments comprising the 1st to 3rd (LigACon1-3), 4th to 7.5th (LigACon4-7.5), 4th (LigACon4), 4.5th to 5.5th (LigACon4.5-5.5), 5.5th to 6.5th (LigACon5.5-6.5), 4th to 5th (LigACon4-5), and 6th to 7.5th (LigACon6-7.5) repeat domains. All 7 recombinant Lig proteins were screened using a slot-shaped dot blot assay for the diagnosis of equine leptospirosis. Our results showed that Li...
Wiedner EB, Lindsay WA, Isaza R.Equine practitioners are sometimes asked to treat zebras or zebra-horse or zebra-donkey hybrids. Although these equids are subject to many of the same health issues as domestic horses, they cannot be handled like horses and generally require heavy sedation to full anesthesia, even for minor procedures. This usually necessitates the use of ultrapotent narcotics administered by remote delivery systems. This article discusses the handling, sedation, anesthesia, and common medical issues of zebras and zebra hybrids.
Selberg K, Easley JT.Dental and sinus disorders are relatively common and of major clinical importance in equine medicine. Advanced diagnostic imaging has become an integral part of equine veterinary medicine. Advanced imaging has progressed the understanding, diagnosis, and treatment of dental- and sinus-related diseases. As a clinician, it is important to realize the value of advanced diagnostic imaging. Although computed tomography and magnetic resonance imaging are both significantly more expensive compared with other diagnostic tools, the financial cost of inaccurate diagnosis and treatment can often result i...
Xie J, Liu G, Tian Z, Luo J.Several approaches have been developed for diagnosis of Theileria equi infection in horses and donkeys but all of them have limitations in practice. Due to numerous strengths including easy operation, cheapness and high sensitivity and specificity, LAMP has been already extensively used for surveillance of a number of diseases. We here set up a LAMP assay based on 18S rRNA gene for T. equi diagnosis. The approach was specific enough to differentiate T. equi from other evolutionary-related protozoa. Moreover, it was sensitive enough that LAMP was capable of detecting as much low as 10 copy targ...
Griffin C.Postpartum evaluation of the foal's head and mouth are performed to detect craniofacial malformations and other congenital defects. Detailed oral examination and diagnostic imaging can provide diagnostic and prognostic information about congenital abnormalities of the mouth or skull. Important abnormalities of foals include wry nose, cleft palate, overbite (parrot mouth), and underbite (monkey mouth, sow mouth). Tumors and cysts can be detected in young horses. In juvenile horses, primary dental care procedures include oral examination, management of sharp enamel points, management of deciduou...
Rawlinson JT, Earley E.Dental therapies for equid incisor and canine teeth have modernized significantly over the last 2 decades. Basic principles in incisor reduction have become more conservative, and extraction procedures more exacting. Periodontal and endodontic treatments are described to save teeth that would have succumbed to extraction in the past. Pathologic impacts on treatment decisions for equine odontoclastic tooth resorption and hypercementosis are significant, and veterinarians and owners need to be aware of treatment options and outcomes. Easy access to equid incisor and canine teeth offers a variety...
Tóth P, Horváth C, Ferencz V, Tóth B, Váradi A, Szenci O, Bodó G.Despite the fact that bone mineral density (BMD) is an important fracture risk predictor in human medicine, studies in equine orthopedic research are still lacking. We hypothesized that BMD correlates with bone failure and fatigue fractures of this bone. Thus, the objectives of this study were to measure the structural and mechanical properties of the proximal phalanx with dual energy X-ray absorptiometry (DXA), to correlate the data obtained from DXA and computer tomography (CT) measurements to those obtained by loading pressure examination and to establish representative region of interest (...
Easley JT, Freeman DE.The diagnosis and treatment of equine dental-related sinus disease is often challenging. Dental-related sinus disease is common and knowledge of these diseases is becoming increasingly important in veterinary medicine. Diagnostic capabilities are continually improving, leading to early diagnostic and therapeutic successes. With advanced imaging modalities, such as computed tomography and magnetic resonance imaging, understanding of the intimate anatomic relationship between teeth and the paranasal sinuses continues to progress. There are many therapeutic options available for the treatment of ...
De Schauwer C, Van de Walle GR, Van Soom A, Meyer E.In the past decade, mesenchymal stem cells (MSC) have received much attention in equine veterinary medicine. The first therapeutic use of equine MSC was reported in 2003. Since then, the clinical application of MSC has been exploding with thousands of horses now treated worldwide. At present, MSC are mainly used in veterinary medicine to treat musculoskeletal diseases based on their ability to differentiate into various tissues of mesodermal origin. This is in marked contrast to human medicine, where MSC therapies are primarily focused on immune-mediated, inflammatory, and ischemic diseases. I...
Harlow BE, Lawrence LM, Flythe MD.Antibiotics are important to equine medicine, but antibiotic-associated diarrhea (AAD) can lead to poor performance and even mortality. AAD is attributed to disruption of the hindgut microbiota, which permits proliferation of pathogenic microbes. The goal of this study was to evaluate the effects of common antibiotics on cellulolytic bacteria, lactobacilli, and AAD-associated pathogens in the feces of healthy horses. Fifteen horses were assigned to three treatment groups (blocked by age and sex): control (no antibiotics), trimethoprim-sulfadiazine (PO), or ceftiofur (IM). Fecal samples (n=8 pe...
Wagnerová P, Sak B, Květoňová D, Maršálek M, Langrová I, Kváč M.A total of 9 (8 stallions and 1 mare) 1 year old ponies were used for the experimental infection caused by Encephalitozoon cuniculi genotype II (10(7) spores per animal). Subsequently, individual horses were slaughtered 7, 14, 21, 28, 35, 42, 49, 56, and 63 days post infection. Immediately after slaughter, tissues samples of stomach, duodenum, jejunum, ileum, caecum, colon, spleen, liver, kidney, bladder, heart, lungs, and brain were sampled. In addition, urine, feces and blood specimens were collected. Enzyme-linked immunosorbent assay was used for determination of humoral immune response and...
Pusterla N, Gebhart CJ.Equine proliferative enteropathy (EPE) is a disease of foals caused by the obligate intracellular organism Lawsonia intracellularis. This emerging disease affects mainly weanling foals and causes fever, lethargy, peripheral oedema, diarrhoea, colic and weight loss. The diagnosis of EPE may be challenging and relies on the presence of hypoproteinaemia, thickening of segments of the small intestinal wall observed upon abdominal ultrasonography, positive serology and molecular detection of L. intracellularis in faeces. Although the clinical entity, diagnostic approach and treatment of EPE are w...
Stratford CH, Lester HE, Pickles KJ, McGorum BC, Matthews JB.Cyathostomins comprise 50 helminth species, considered the most problematic equine endoparasites. Three classes of anthelmintic are currently licensed for their control, namely the benzimidazoles (fenbendazole), tetrahydropyrimidines (pyrantel) and macrocyclic lactones (ivermectin and moxidectin). Anthelmintic resistance in cyathostomins is common. With no new classes expected in the near future, it is essential to determine the efficacy of the available anthelmintics to inform future control programmes. Objective: To determine the efficacy of all 3 anthelmintic classes against strongyles in e...
Denoix JM, Jeffcott LB, McIlwraith CW, van Weeren PR.This manuscript describes a new classification of the various joint-related lesions that can be seen in the young, growing horse based on their anatomical and functional aetiopathogenesis. Juvenile osteochondral conditions (JOCC) is a term that brings together specific disorders according to their location in the joint and their biomechanical origin. When a biomechanical insult affects the process of endochondral ossification different types of osteochondrosis (OC) lesions may occur, including osteochondral fragmentation of the articular surface or of the periarticular margins, or the formatio...
Boyen F, Smet A, Hermans K, Butaye P, Martens A, Martel A, Haesebrouck F.The use of β-lactam antibiotics results in the selection of bacteria showing resistance toward this class of antibiotics. The review focuses on the increasing importance of methicillin resistant staphylococci and broad-spectrum β-lactamase-producing Enterobacteriaceae in horses. Diagnostic protocols that optimize accurate identification of these bacteria from both clinical samples and samples obtained from putative carrier animals are described. In addition, the opportunities and pitfalls for preventive and curative measures are discussed.
Amer MM, Desouky AY, Helmy NM, Abdou AM, Sorour SS.Strongylid and non-strongylid nematodes are one of the most important parasites infecting equines. The traditional method to identify these nematodes is through coproscopy and fecal culture. Because of the scarcity of data published in Egypt discussing the morphometric features of infective 3 larvae of these nematodes, this study aims to provide a morphometric key for L3 of common strongylid and non-strongylid nematodes infecting Egyptian equines. For this reason, we cultured fecal samples containing GINs eggs and 3 larval stages were identified based on their morphology (i.e., shape and numbe...
Rossi M, Gonzalez-Castro R, Falomo ME.Different additives have been tested in cooled stallion sperm, in order to maintain sperm quality and to ameliorate the decrease in sperm fertility potential. In several species, caffeine and pentoxifylline promote sperm motility by increasing energy production. We evaluate the effects of caffeine and pentoxifylline when added to stallion sperm before or after cooling. Three ejaculates from five stallions each were processed and resuspended in skim milk extender. Caffeine (5 mM), pentoxifylline (3.5 mM), or both additives combined were included to sperm before or after cooling (4°C for 24 ...
Hirsch E.Medical diagnosis is typically an iterative process guided by integration and synthesis of data into a model of disease. However, facts are not the only inputs into this process. A case of medical mis-diagnosis is presented, in which systematic cognitive bias is considered to have played a role in generating error. Specific cognitive biases are cited, and measures that can be taken to minimize their negative impact are reviewed.
Nemoto M, Tamura N, Bannai H, Tsujimura K, Kokado H, Ohta M, Yamanaka T.Baloxavir marboxil (BXM), an inhibitor of the cap-dependent endonuclease of the influenza virus polymerase acidic protein (PA), exerts an antiviral effect against influenza A virus. It has been available in Japan since March 2018. This study evaluated the antiviral efficacy of BXM against equine influenza A virus (EIV) by an experimental challenge study using horses. Six horses were experimentally inoculated with EIV, and BXM was administered to the three horses at 2 days post inoculation. Horses treated with BXM showed milder clinical signs than horses without treatment and shed less virus. T...
Barakzai SZ, Boden LA, Dixon PM.To evaluate the effect of laryngoplasty (LP) on race performance in longer distance (National Hunt) Thoroughbred racehorses. Methods: Case-control study. Methods: National Hunt Thoroughbred racehorses (n=71) and race-matched controls (n=126). Methods: Race records for National Hunt racehorses that had LP and ventriculocordectomy were analyzed and racing performance was compared with race-matched controls. Results: Sixty-three of 71 cases were matched with controls. Postoperatively, 78% of cases raced, 47% improved their individual performance and cases were as likely to start in 1 or 3 races a...
Catalán J, Yánez-Ortiz I, Gacem S, Papas M, Bonet S, Rodríguez-Gil JE, Yeste M, Miró J.Previous research has determined that irradiation of mammalian sperm with red light increases motility, mitochondrial activity, and fertilization capacity. In spite of this, no study has considered the potential influence of the color of the straw and the extender used. Therefore, this study tests the hypothesis that the response of mammalian sperm to red light is influenced by the color of the straw and the turbidity/composition of the extender. Using the horse as a model, 13 ejaculates from 13 stallions were split into two equal fractions, diluted with Kenney or Equiplus extender, and stored...
Lewis N, Schnauffer K, Hinrichs K, Morganti M, Troup S, Argo C.The use of time-lapse imaging (TLI) in the evaluation of morphokinetics associated with invitro developmental competence is well described for human, cattle and pig embryos. It is generally accepted that embryos that complete early cleavage sooner are more likely to form blastocysts and that timing of later events, such as blastocyst formation and expansion, are predictive of implantation potential and euploid status. In the horse, morphokinetics as a predictor of developmental competence has received little attention. In this study we evaluated the morphokinetics of early equine embryo develo...
Karasek I, Butler C, Baynes R, Werners A.Ectoparasites infestations are a growing concern to horse owners and equine veterinarians alike. Ectoparasites cause significant health and welfare issues and can potentially can serve as vectors for a variety of pathogens. The prevalence of ectoparasites increases around the world, and especially in horses information on the successful prevention and treatment of ectoparasite infestations in scarce and in many instances anecdotal. This poses a challenge to the equine veterinarian and off-label use of drugs can lead to detrimental effects in horses. In this review we describe the current avail...
Fernie DS, Batty I, Walker PD, Platt H, Mackintosh ME, Simpson DJ.The vaccination of four ponies on two occasions with a formolised culture of Haemophilus equigenitalis produced a high circulating antibody titre to the organism in each pony. Three out of four vaccinated and all of three unvaccinated ponies developed typical symptoms of contagious equine metritis (CEM) when subsequently challenged with a vaginal exudate containing H equigenitalis. Similarly, three ponies which had previously been infected with H equigenitalis and which had recovered spontaneously also developed contagious equine metritis when rechallenged with the organism. The clinical and b...
Fischer AT, Spier S, Carlson GP, Hackett RP.In 6 horses with urinary bladder neoplasms, common clinical findings included a palpable mass in the bladder, anemia, hematuria, and/or proteinuria. Squamous cell carcinoma was found in 4 horses and appears to be the most common bladder tumor in the horse. Single cases of transitional cell carcinoma and fibromatous polyp also were identified. All horses except one were over 10 years of age. In one mare, treatment with 5-fluorouracil intracystically resulted in decreased bleeding from the bladder mass and apparent stabilization of the mass size. The mare ultimately died because of abdominal met...
Perez-Ecija A, Mendoza FJ, Estepa JC, Bautista MJ, Pérez J.A 2-month-old foal with septic shock and severe respiratory distress was referred to the Veterinary Teaching Hospital. Due to poor prognosis, the foal was euthanized. Histopathology showed lesions suggestive of Rhodococcus equi infection associated with a diffuse interstitial infiltrate of foamy macrophages and syncytial cells presenting large acidophilic intranuclear inclusion bodies, fibrin exudates and hyaline membranes. Bacteriological examination from lung and respiratory exudates confirmed R. equi infection, whilst immunohistochemistry and PCR yielded a positive result for Equid herpesvi...
Baldwin CM, Smith MRW, Allen S, Wright IM.Slab fractures of the third carpal bone (C3) are a common injury of Thoroughbred racehorses. Results of arthroscopically guided repair have not been reported since the initial description of the technique in 1986. Additionally, fracture details and racing outcomes in a population of Thoroughbreds racing under UK jurisdiction have not previously been described. Objective: To report the frequency distribution of C3 slab fractures and to determine the impact on racing performance following arthroscopically guided repair in a population of Thoroughbred racehorses. Methods: Retrospective case serie...
Shaw K, Ursini T, Levine D, Richards J, Adair S.Core strengthening and postural stability are desired outcomes of certain therapeutic exercises performed in horses. This study aimed to quantify changes in muscle activation at a walk and trot in horses traveling over eight consecutive ground poles evenly spaced (at 30 inches for walk and 48 inches for trot) in parallel fashion in a straight line, and with hindquarter and abdominal elastic resistance bands applied at 25% stretch. Surface electromyography (sEMG) data were collected for the longissimus dorsi and rectus abdominus muscles in six horses. A 2 × 2 repeated measures ANOVA was perf...
Wahl K, Adams SB, Moore GE.To assess fetlock joint contamination with tissue debris and hair after arthrocentesis. Methods: Experimental. Methods: Fetlock joint tissues (n = 10 horses). Methods: Soft tissue flaps including the joint capsule were dissected from the dorsal fetlock joints of 7 anesthetized horses leaving an intact proximal base. Needles inserted through the tissue flaps were flushed into tissue cell culture plates and examined for debris. Studies were repeated on excised fetlock tissue preparations after being stored for 5 days. Variables included gauge and type of needle, insertion of spinal needles with ...
Sanders-Shamis M, Bramlage LR, Gable AA.The case records, radiographs and treatment results of 47 consecutive equine radius fractures presented to The Ohio State University Veterinary Hospital from 1975 to 1985 were examined retrospectively. Chip fractures and incomplete fractures were not considered. Both diaphyseal fractures and fractures involving the physes were included. Diaphyseal fractures were placed into three major categories: comminuted, oblique and transverse; and subclassified as proximal, mid-diaphyseal, or distal. Fractures involving a physis were classified using the Salter-Harris classification system. The horses ra...
Orsini JA, Baird DK, Ruggles AJ.A 7-year-old female Thoroughbred was admitted with a history of labored breathing, stridor, and exercise intolerance. Examination revealed a mass in the left paranasal sinuses that was determined to be an ossifying fibroma. Initial treatment consisted of surgical removal of the mass alone; however, the mass recurred 9 months after surgery. The mass was again removed, and adjunctive radiotherapy consisting of 3,000 cGy of cobalt radiation was administered. This time, the tumor did not recur for > 6 years. A third surgery was performed to remove the mass, and adjunctive radiotherapy consisting o...
Martin CA, Kerr CL, Pearce SG, Lansdowne JL, Bouré LP.To determine reasons for epidural catheter placement among horses examined at a veterinary teaching hospital, efficacy of epidural administration of analgesics, duration of catheter placement, reasons for catheter removal, and complications encountered. Methods: Retrospective study. Methods: 43 horses. Methods: Medical records were reviewed. Results: A total of 50 epidural catheters were placed in the 43 horses. Underlying conditions included fractures, lacerations, septic arthritis, myositis, perineal injuries, and cellulitis. Horses ranged from 2 to 21 years old and weighed between 365 and 7...
Maniego J, Pesko B, Hincks P, Taylor P, Stewart G, Proudman C, Scarth J, Ryder E.The misuse of gene therapy by the introduction of transgenes via plasmid or viral vectors as a doping agent is an increasing concern in human and animal sports, not only in consideration to fair competition but also in potential detrimental effects to welfare. Doping events can be detected by polymerase chain reaction (PCR) amplification of a transgene-specific region of DNA. Quantitative real-time PCR (qPCR) is particularly suited to confirmatory investigations where precise limits of detection can be calculated. To fully validate a qPCR experiment, it is highly desirable to confirm the ident...
Sharman P, Young AJ, Wilson AJ.Effects of parental age on offspring viability have been reported in a wide range of species. However, to what extent parental age influences offspring traits beyond viability remains unclear. Moreover, previous research has primarily focused on maternal age effects. The purpose of this study was to test for paternal and maternal age effects on offspring speed in thoroughbred racehorses. We analysed over 900 000 race performances by over 100 000 horses on British racecourses between 1996 and 2019. With knowledge of the age of all 41 107 dams and 2 887 sires at offspring conception, we jointly ...
Ellerbrock M, Wehrend A.In horses, birth is classified as dystocia when the process of parturition threatens to inflict damage onto the mare or the foal, when assistance is required to complete the process of parturition, or when there are temporal deviations in the physiological duration of the first and/or second parturition stages. In this, the duration of the second stage is an important indicator in identifying dystocia, as this phase is easily discernible by the mare's behavior. Equine dystocia is classified as an emergency with life-threatening consequences for mare and foal. A large degree of variation has be...
Burns TA.Endocrine diseases, such as equine metabolic syndrome and pituitary pars intermedia dysfunction, are common in domesticated horse populations, and the frequency with which these diseases are encountered and managed by equine veterinary practitioners is expected to increase as the population ages. As clinicians learn more about the effects of these diseases on equine reproductive physiology and efficiency (including effects on reproductive seasonality, ovulation efficiency, implantation, early pregnancy loss, duration of pregnancy, and lactation), strategies and guidelines for improving fertili...
Bucki EP, Giguère S, Macpherson M, Davis R.The objectives of this study were to investigate the pharmacokinetics of once-daily amikacin in healthy neonates, to determine amikacin concentrations in hospitalized foals, and to determine the minimum inhibitory concentrations (MICs) of amikacin against gram-negative isolates from blood cultures in septic foals. Median half-life, clearance, and volume of distribution of amikacin in healthy 2- to 3-day-old foals after administration of an intravenous bolus of amikacin (25 mg/kg) were 5.07 hours (4.86-5.45 hours), 1.82 mL/min/kg (1.35-1.97 mL/min/kg), and 0.785 L/kg (0.638-0.862 L/kg), respect...
Lane JG, Longstaffe JA, Gibbs C.The clinical and radiographic features of 15 cases of paranasal sinus cysts are described. Breed, sex and side frequency were unremarkable but two distinct categories of age incidence emerged. Onset of signs had occurred before one year of age in three cases, while all but two of the remaining 12 animals were older than nine years. The most common clinical signs were nasal airway obstruction, facial swelling and nasal discharge, often occurring in combination. Radiographic changes were recorded in all horses. Sinus opacification was a consistent finding and in several cases the bone surroundin...
Klein CE, Bramlage LR, Stefanovski D, Ruggles AJ, Embertson RM, Hopper SA.To compare 3 different methods for treatment of medial femoral condyle (MFC) subchondral cystic lesions in Thoroughbred horses <24 months old based on the criterion of ability to race post-treatment. Methods: Retrospective cohort study. Methods: Thoroughbreds (n = 107, age < 24 months) diagnosed with MFC subchondral cystic lesions. Methods: Medical records between January 2004 and December 2017 were reviewed. Three treatment methods were used in these horses during that time frame: arthroscopic debridement, intralesional autologous mesenchymal stem cell (MSC) injection, and int...
Cuvelliez SG, Eicker SW, McLauchlan C, Brunson DB.Anesthesia of equids is associated with pulmonary dysfunction. Cardiovascular and respiratory effects of inhalation anesthetic agents and duration of anesthesia have been studied, using oxygen as the carrier gas. To our knowledge, the effects of inspired oxygen have not been determined. We studied the cardiovascular and respiratory effects of 2 inspired oxygen fractions (0.30 and greater than 0.85) in 5 laterally recumbent, halothane-anesthetized horses. Mean systemic arterial blood pressure, cardiac output, central venous pressure, pulmonary arterial pressure, arterial pH, and arterial base e...
Humblet MF, Saegerman C.The present paper proposes a tool to follow up the compliance of staff and students with biosecurity rules, as enforced in a veterinary faculty, i.e., animal clinics, teaching laboratories, dissection rooms, and educational pig herd and farm. Unassigned: Starting from a generic list of items gathered into several categories (personal dress and equipment, animal-related items, infrastructures, waste management, management of material/equipment and behavior), a checklist was created for each sector/activity mentioned above, based on the rules and procedures compiled in the Faculty biosecurity st...
Jelinski MD, Schreiner B, Neale A, Townsend HGG.A workforce survey of private veterinary practices in western Canada was conducted in 2020. Data were obtained on 526 practices (response rate = 39.5%) and 1445 individual veterinary practitioners. Overall, 68.4% of practitioners identified as female, with 4 times as many females as males comprising the youngest age cohorts (26 to 35 y) of the profession. The majority of practices (67.9%) were companion animal, followed by mixed animal (21.9%) and food animal (10.2%). Most females (77.2%) and males (57.8%) were engaged in companion animal practice, whereas 23.5% of males and 6.0% of females we...
Popot MA, Bonnaire Y, Guéchot J, Toutain PL.Hyaluronic acid (HA) is an endogenous glycosaminoglycan used in the treatment of joint diseases, but medication control is required by horseracing authorities. Therefore, a medication control policy needs to be established. Objective: To establish physiological plasma HA concentrations in post race horses, determine the HA endogenous production rate and document the disposition of HA after i.v. and intra-articular hyaluronic acid administration at recommended therapeutic doses. Methods: Hyaluronan concentrations in plasma were determined using an ELISA specific test; concentrations in synovial...
Sullins KE, White NA, Lundin CS, Dabareiner R, Gaulin G.Treatments addressing variously theorised pathophysiological mechanisms of small intestinal adhesions have been reported. This study applied those classes of treatments to the most clinically relevant aetiology of post operative adhesions. Objective: Treatments addressing the pathophysiology of ischaemia-reperfusion induced adhesions would accordingly reduce the incidence of adhesions from this model. Methods: Four classes of treatments were administered for 72 h to 16 foals subjected to complete ischaemia followed by reperfusion to create peritoneal adhesions. These groups were: 1) FPG group-...
Traub-Dargatz JL, Weese JS, Rousseau JD, Dunowska M, Morley PS, Dargatz DA.Reduction factors (RFs) for bacterial counts on examiners' hands were compared when performing a standardized equine physical examination, followed by the use of one of 3 hand-hygiene protocols (washing with soap, ethanol gel application, and chlorohexidine-ethanol application). The mean RFs were 1.29 log10 and 1.44 log10 at 2 study sites for the alcohol-gel (62% ethyl alcohol active ingredient) protocols and 1.47 log10 and 1.94 log10 at 2 study sites for the chlorhexidine-alcohol (61% ethyl alcohol plus 1% chlorhexidine active ingredients) protocols, respectively.
